AI system GEMS accelerates molecular structure identification

By PulseAugur Editorial · [1 sources] ·

Researchers have developed GEMS (Guided Editing of Molecular Structures), a novel AI system designed to identify small-molecule structures from mass spectrometry data. GEMS utilizes a pretrained spectrum-to-fingerprint model called MIST and a neural policy to refine candidate structures through learned bond edits. This approach significantly speeds up the identification process, achieving higher accuracy in minutes compared to previous methods that took hours. The system demonstrates strong performance on benchmark datasets like NPLIB1 and MassSpecGym, outperforming existing baselines. AI

IMPACT Accelerates discovery in metabolomics and natural-product research by significantly reducing the time and improving the accuracy of molecular structure identification.

    GEMS: Molecular Structure Elucidation as Learned Search over Isomer Graphs

    arXiv:2610.23617v1 Announce Type: new Abstract: Identifying small-molecule structures from molecular formulas and tandem mass spectra remains a bottleneck in untargeted metabolomics and natural-product discovery. Even when database retrieval or de novo prediction misses the exact…
